So some more testing.
I tried to make it as comparable as possible. I started the patches let them sit for a minute. Started the playback let it run for 1:30 min an then made the screenshots. The patches without the “benchmarking” seem to run a bit smoother.
First of all, the SlimDX version I added performs abysmal, it reaches max 12 FPS :) Comparing the CPU load to the other approaches I assume some of the “copying” back and forth happens on the CPU. Also there is some error at startup.
Beta using woei’s player again 180 FPS but this time I had some dropouts here and there.
Gamma using @Elias’ improved version I also got to 180FPS with some dropouts. After I made the screenshots I realized that I had set GraphicsResourceUsage to Default but trying with Immutable yielded the same results. So this seems the way to go.
Here again the patches with the settings I used in case someone else wants to give it a go:
Player.DX11Texture.7z (15.4 KB)
TextureLoader.vl (137.0 KB)
